The first question you should find an answer for is how are you going to communicate all that power to the ground? Just spinning the tires without quickly going forward is a useless waste of rubber and effort.OK so i am still waiting to hear something about my block, but while i wait i decided to go ahead and price 2 differing builds... the first is the 351 the second is the 393....
I now have the heads to support either variant of the engine, my blower moves more CFM than either can use = blower will make boost....
I have to buy pistons/rings for both
-the cost between the two is very similar, within $200.. both aiming for a 9.5 compression ratio for the boost.
What direction should i lean? i cant decide.
351 OR 393
not sure... the rod ratio is 1.54 on a 393 with a stock rod... thats pretty close to the ls7 rod ratio and they dont seem to have any issues....Rod angle and ring seal should be what you look at...a 393 has problems with at least one of those.
